An integrated approach to controlling brucellosis in Africa

Introduction to the meeting

Delia Grace

Workshop: An Integrated Approach to Controlling Brucellosis in Africa, Addis Ababa, 29-31 January 2013

Research Firsts for Africa

1. Earliest lesions compatible with brucellosis found in hominin skeleton in South Africa, dated to around1.5 myo.

2. In 1921, Bevan, a vet in Zimbabwe first suggested that B. abortus could be zoonotic.

3. ‘Bakkale’ recognised by Fulani as a disease causing abortions & hgyroma. Confirmed as brucellosis in the 1940s.

African livestock sector today

1. Many farmers, livestock and consumers. High preferences for animal source foods.

2. An important role for women in livestock production, processing, retail and food preparation.

3. Wildlife uniquely important and present opportunities and risk.

4. High levels of disease, yet low levels of reporting.

Importance of women

• 1% of African women own land but 10% own livestock

• Usually responsible for poultry, animals at the homestead,

watering, feeding and looking after sick animals

• High involvement processing and sale of ASF

• Prepare most food for household consumption

• Giving women the same

resource access as men

would add 20-30% to

farm yield (source: FAO, 2011)

Zoonotic EID events 1930-2012 not from wildlife

Zoonotic EID events 1930-2012 from wildlife

•75% ZEID emerge from wildlife

• Major reservoir of important diseases including brucellosis

•Wildlife an increasingly scarce resource

•Bush-meat important for income and food

Wildlife an opportunity and risk

9

High levels of avoidable livestock disease

• Transboundary animal disease

• Production disease

• Zoonoses

• Food borne disease

• Emerging disease

Status quo brucellosis in Africa

• Over 800 studies

• Present cattle, camels, shoats, horses, pigs, dogs, poultry, wildlife

• Average prevalence 10.5% in animals and 8% in people

• Reduce production by 8% per annum

Expectations for the workshop

• Evidence on prevalence and impact of brucellosis

• Share experience on what works and what is to be avoided

• Provide forum for conversations, networks, publications, awareness

• Lead to plans, proposals and new investment in tackling brucellosis
